Raspberry Pi Zero 2W periodically disconnects from WiFi

At least I have no other idea. You could try using a different access point or use your mobile phone as hotspot to see if your device will survive. Probably think of an usb to ethernet adapter to work around.

I bought a usb to ethernet adapter. This bug is still really interesting.

Thank you all for the help provided, this is a beautiful community!

hope it will help to improve your situation and stability.

Sorry, I’m having the same issue, but even worse. Please advise if it’s better for me to create a new topic instead.

I never can get it onto the WiFi, starting it up at a strength of -15dBm and speed at 72.2Mb. However, I haven’t yet seen any data passing through yet. I guess it’s likely going thru my eth0 interface since it’s connected to an ethernet adapter.

Any advice? Thanks.

P.S. Would you mind sharing what adapter you got for your Zero 2W? I had a terrible experience in getting a right adapter for my Zero2W, and because of this, I turn my attention to WiFi instead of using an ethernet adapter.

Today, I started everything from scratch and set up everything with dietpi.txt and dietpi-wifi.txt. Here is the parameter I modified:
AUTO_SETUP_NET_WIFI_ENABLED=1 (I leave the AUTO_SETUP_NET_ETHERNET_ENABLED=1 unchanged).

I did make changes on other parameters, but I guess they won’t interrupt the wlan / eth:

  1. AUTO_SETUP_SWAPFILE_SIZE=0
  2. AUTO_SETUP_HEADLESS=1

With this, I have the Wi-Fi port enabled and working, but this time the eth0 was down and I couldn’t get it up.

Would sb shed some light on how I can get both eth0 and wlan0 up and running? Thank you very much.

you can check ip a if the interface is visible.

Zero 2W has wifi issue from beginning for me too.
I saw firmware crash more times with bullseye and in related forum topics nobody knows a solution for that.
I upgraded to bookworm release with the dietpi script and compiled a custom ver. 6.6 kernel. I didnt see a wifi firmware crash anymore but suffering connection drop in random interval which seems generated by that connection will be packet loss and the DietPi-WiFi_Monitor service drop the whole connection instantly and reconnects. I see nothing interesting in logs.
